A 15-year-old Perkasie High School student will be charged as an adult with an attempted rape of a student Friday in the school's bathroom.

Police have not yet identified the boy, but said he will be charged as an adult.

According to a news release:

Around 6:45 a.m., police were called to the high school at 1228 N. Fifth St. for a reported sexual assault.

Police said the teen was armed with a knife and forced a girl into the men's bathroom and attempted to sexually assault her.

Police said a high school teacher intervened and was also threatened by the teen.

Police said the boy will be charged with attempted rape, sexual assault, false imprisonment, possession of a weapon and simple assault.

In a statement on the high school's website, school officials said only that the two students were involved in an incident "that required intervention by staff and police." No one was injured and the building is secure, the statement reads.
